Answer:
7*7
Step-by-step explanation:
49 = 7*7
As 7 is a prime number ( a number that can only be written as a product of 1 and itself), we are finished
A verbal statement is an expression that uses words instead of numbers. A math verbal model is when a mathematical model is completely written out in words instead of numerals. Most real world problems are stated using words and need to be translated into mathematical statements.
Answer:
Problem 1: n = 16
Problem 2: n = -1
Step-by-step explanation:
Problem 1:
-3n + 48 = 0
We solve the equation for n.
First, subtract 48 from both sides.
-3n = -48
Now divide both sides by -3. This cancels out the negative on both sides:
n = 16
-2n + 10 -5n = 17
First, combine the terms with n:
-7n + 10 = 17
Now, combine the numbers that don't have n (subtract 10 from both sides).
-7n = 7
n = -1
Answer:
The mother is 30 and the daughter is 6
Step-by-step explanation:
When solving for this, you can derive the equations
x=5y and x+6= 3(y+6)
x= mother and y= Daughter
Solve the equations by substituting the first equation into the places of x in the second equation to get the value of x. Next, pug in the value of x and solve for y.
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
